LINOTYPE -MAOHINE Specification of Letters P at'ent.

, Patented June 2, 190a.

To all whom it may concern:

Be it known that I, DAVID S. KENNEDY, of

borough of Brooklyn, county'fof Kings, and

State of New York, have invented-a new and u eful Improvement in Linot"e-Machines,

e following is a specification.

chines of the general organization represented in' Letters Patent of thev United States #436,532; In these machines, type metal slugs,bearing-on one'edge the'characters to print'an entireline, are cast'in aslotted mold agamst an assembled line of.-- matrices. The mold is mounied in a vertical 'intermittingly rotating whee bywhichit ispresentedfirst inahorizontalcasting position, and thereafter in avertical position in front of the reciprocating ejector-blade, by. whichthe contained slug is driven edgewise from the mold and between two.parallel trimming knives into the receivinggalley atthe front, The hotmetalshaved from the side faces of the slug' by the knives clings withconsiderable tenacity to their edges, and'un'less removed, the shavingsare liable to lodge upon and impair the faces of succeeding slugs. Forthls reason, all machines, of thisolass'are provided with .wipersof oneform or another to remove the, adhering.

metal from the-knives after eachi'shavi'ng. ope'ration.-; As heretoforeconstructed, wip

ing mechanism'shave' been open to various objections such as 7 theiropmplexity, their dependence upon; springs, their liability to stop inthe path 'of the ejector-blade, etc. My invention relates to animproved, form .In the drawings,' ,-Figurel1' is- I a perspective viewof the knives and thewi-ping 111G011:

the line of matrices-andpresenting t e same ide. vertically in'themain-frame; and has a .fixed travel ongitudinally over t frame. r V g Fisan actuating link, pivoted atone endtolthewiper-rod E, and atthe otherend to a 'ives presenting arallel edges be-f length, ofltravel. far 'asdescribed, the parts are of ordinary construction,

, Dre resents the lm'ife-wilper designed to e edges of the twoknives incontact therewith,.or in close proximity thereto,- the latterarrangementeirlg preferred. This .wiper,-which-1s preferably in the formof a metal plate, but whichmay be a brush or a pad of 'felt or othersuitable material,,is attached to the upper end of a vertical rod E,which is guided at its upper and lower endsin the mainlever-G whi'chismounted at its middle on a horizontal stud orpivot g on the main-frame.The leverG is actuated by a stud ,or-roller-H on the elevator-slide C,as shown in" and, 2. The elevatorO has a; movement Figs. "1 I greaterthan that required of the knife-wiper,

and its movements arearrested at such points and at such times that apositive connection between the elevator and the wiper-rod isimpractical; For these:reasons,'and in order thatthe knife-wiper mayremain at rest in the-required position while the elevator C is inmotion, I provide for lost motion between theelevator-slide andthe leverby giving the 7 "forward "end of thelever the form shown'in. Figs. 1 and2, that is to'say, with a riotch g" 1 I its .upper portion, and anextended outer surface g' beIOW the notch.

Duringthecasting action, the partsstand in'the position shownin Fig. 1,withjthe stud H bearm on the flat surface of the ever, and Y holding ite latterand the .wiper D-.in their. up ermost-ip'o'sitions- As theelevator-rises su seduentfto' the casting aotion., the roller travelsupward-on the surface g -while the wiper remains at, rest, until finallythe roller enters-the notch g as shown in Fig. 2,

whereupon it-tans es the lever to move and draw the wiperD downward theentire length a of the knives. Asfthe elevator descends, the lever ispositively actuated bythe stud H ,tr'av'elin downward in the'slot g andthrow-. ,ingthe' ever to the position shown'in full lines in Fig.1, andthe knife returned to its u permost position and there held at rest w hl e the elevator C com letes its downward movement. As. the'lmi ereaches its upper+ most position, the surface g assumes a verticalposition and] the lever remains at-rest while the stud continues totravel downward being no possib over said surface. It will be observedthat the knife is moved positively in both direc-- tions and through'adefinitedistanoe, there ity of its failin to move or of its beingarrested in-the P8151 of the-Sadvfancing ejector. The essence. f theinventionlies in moving the knife positively in both directions througha device receivin motion from the elevator C, and in so forming theparts as to permit the dwell or rest of the wiper while. the elevatorcontinnes-tomovef I In machines used for certain purpo'ses,it iscustomary to use a single knife trimming one side of the slug only. Itwill, of course, be understood that mywiping mechanism-may be used insuch case In connection with a?- single knife, :and that sucharrangementwill fall within the limits of my invention and theclaimshereinafter stated.-

' It will be obvious; torthe" skilled mechanic 'thattheform' of theforward end of the lever said lever having one end provided with the'.notchlg and surface 9 G may be modified without changing its mode ofaction; for example, it may be eX- tended as shown 'in'dotteddines inFig. 2, so as to form an ,angulanslot inclosing the roller H.
